Blender crashes entire PC on Cycles rendering - need help diagnosing the problem
This is most definitely a hardware issue; but don't despair, the fact that it isn't with Blender doesn't mean it can't be fixed. I rendered it on 3.0a on my own machine (desktop, Linux Mint, FX-8300 processor with a GTX 1660 GPU) and it rendered fine.

That looks like a laptop screen, and if I'm right, the first thing I would suggest doing is checking its operating temperature. If you've got an RTX 2080 in there it can't be more than a few years old; but you would be amazed at what I've seen a little stray cat hair do. Cooling mats exist for this very reason, though to be fair, it's also why I stay the heck away from rendering on a laptop when I'm anything short of desperate. But, you use what you've got.
I'm also noticing that your i9-9900K, which is rated for around 3.60 GHz, is reportedly jumping to 4.55 GHz, which causes a massive heat output increase. (Massive.) Do you have your machine overclocked in its UEFI settings? Because for 3D modeling, overclocking is definitely not your friend, and you should consider switching it all off and waiting on it. There's a very good reason that those aren't the factory settings. This would also explain the wait time of a full minute before your entire machine goes down.
If neither of these is working, then the traditional debugging method is to simplify until it stops happening, and then isolate the probable cause. For &quot;any cycles render&quot;, does that mean even for the default cube with no material added? At any resolution? Have you checked the Blender error log, traditionally (on Windows) at C:\Users[your username]\AppData\Local\Temp\ ? That may contain useful information for you. (They always end in &quot;.crash.txt&quot;, though I haven't rendered on that OS in a long time.)
I would suggest turning off any overclocking settings if you've switched them on, and grabbing a cheap cooling mat. If it doesn't do the job, most stores will accept them for returns. Nine out of ten it's your temperature getting out of control. Grabbing some electronics-safe compressed air, and maybe some cotton swabs and rubbing alcohol, and cleaning out the vents won't hurt you either. At minimum you should keep it elevated enough for proper heat exchange. (In a pinch after a hurricane, I once managed that with a cooking grill... long story.)
Hopefully that will help you get to the bottom of this. Good luck! And props on the H✭R poster, you make me feel less old.
